Katie Lee Joel, 26, certainly enjoys being the wife of Billy Joel, 58. The pair, who celebrate their third anniversary today, are perfect for each other. “We complement each other,” she tells me at VH1’s Save the Music Tenth Anniversary Gala. “Obviously there’s a big age difference, but he’s very immature and I’m very mature so we meet in the middle.” What’s one perk of being Mrs. Billy Joel? Sweet-toothed Katie gets Graeter’s ice cream shipped in regularly from Cincinnati, Ohio. “Food is what brought us together,” she says. “We love to go out to eat, and we love to cook at home. We’re always trying something new. He loves my peach cobbler, and he loves my meatloaf. Those are his two favorites.”
